21 Travel Rule is on-premises compliance software for virtual asset service providers (VASPs) that need to exchange required information for cryptocurrency transactions under the FATF Travel Rule. It provides a Compliance Dashboard and GraphQL API for managing VASP-to-VASP transfers, reviewing transaction details, applying pre-transfer approval rules, and exporting records. The software supports the Travel Rule Protocol and access to the TRUST network for participating counterparties. For transfers involving self-hosted wallets, its AOPP Portal collects wallet-ownership proofs and maintains an auditable verification registry. Deployed in a customer's environment, 21 Travel Rule keeps Travel Rule data on-premises. It is designed for compliance and technology teams at crypto exchanges, banks, VASPs, and other financial institutions handling virtual assets.
